I think you mix up two different things: configuring a 3 zone cymbal to produce different notes for different zones and setting up those notes to match sounds in the drum soft synth. To address the first thing:
1. Forget about about your soft synth, just don't run it.
2. Take a screenshot of MDM settings showing how you configured the cymbal with all 3 zones having different Notes.
3. Hit each zone a few times and take a screenshot of MIDI Log in MDM.
To address the second thing you have to sort out the first thing first.
